wall of the box body is cut away to display the contents of the box fromthe front' when the hinged cover is in open position, wherein the saidfront wall cooperates with the cover to secure u the latter iniclosedposition and further serves to provide support for the cover to preventsagging or inwardly crushing of the cover under pressure from above,such as when a number of boxes are piled one upon the other.

u Another feature of the invention is to provide a box in which thecut-away front wall is reinforced by forming the same of a doublethickness to support the front end of the hinged cover under anyordinary pressure or load to which the cover may be subjected.

A further feature of the invention is the provision of cardboard box inwhich the front flap of the hinged cover may be guided into its properinterfitting position with respect to the -front wall of the box body tofacilitate and expedite the swinging of the cover to fully closedposition.

A still further feature of the invention is to provide a cardboarddisplay box having the above mentioned improvements which does notincrease the cost of the box over previous cardboard boxes of thisgeneral type.

Other features of the invention will appear as the followingspecification is read in conjunction with the accompanying drawings, inwhich:

Like reference characters refer to like parts throughout the severalforms of the .invention herein described.

Referring to the drawings by reference characters, thenumeral I 0designates the preferred form of my cardboard box in its entirety andwhich is of rectangular shape in configuration, although the inventionabout to be described may be embodied in boxes of other shapes ifdesired. The box I0 includes a body II comprising a bottom wall I2,parallel upstanding side walls I3-I3, a. rear end wall I4, an innerrelatively low front end wall I consisting of overlapping flaps ISH-I5alwhich are respectively formed integral with the side walls I3I3, and anouter front end Wall I6 formed integral with the bottom wall I2. Formedintegral with and extending inwardly from the top ofthe side walls I3I3are flaps I'I-II. Acover I8 is hinged to the top of the rear end wall I4as at I9 and has a hinged downwardly extending front flap 2l) at thefront end thereof.

The box I0 including the body II and hinged cover I8 may be constructedfrom a single blank of `cardboard folded into the set up position asillustrated in the drawings, vor the box maybe made of two or morefoldable blanks pasted, stitched, or otherwise secured together. Theessential features of the invention will be more fully explainedhereinafter.

The inner front end wall I5 is cut inwardly from the top as at 2| sothat each flap I5a is provided with an upwardly extending front cornerextension 22, the inner side edges of the flap extensions22 convergingdownwardly so that the opening in the frontof the body is wider at thetop than at its bottom.

Formed integral with the outer front wall I6 is a lock flap 23 hinged onthe fold 24, the same being of a height equal to the height of the frontwall flaps I5a and which lock flap has spaced tongues 25-25. The lockflap 23 is of a width equal to the width of the bottom of the opening inthe front and is folded inwardly through the opening and fiat againstthe inner sides of the flaps I5 of the inner front wall I5 as bestillustrated in Figure 5 of the drawings. The tongues 25-25 enter slots26-26 in the bottom wall I2 at the front end thereof to secure thefolded lock flap 23 against accidental unfolding. The lock nap 23 whenin locked position acts to prevent outward separation of the lappingfront flaps I5a and thus holds the front end of the body II in rigid setup position.

The cover locking flap 20 .is provided with a tongue' extension 21 whichis of a, width equal to the width of the fold 24 of the flap 23 anddisposed on opposite sides of the tongue extension 21 arerelativelyshort semi-circular shaped tongues 28-28. Notches 29--29 areformed between the inner edges of the tongues 28 and the side edges ofthe tongue extension 21. When the hinged cover` I8 is swung to closedposition over the body II, the tongue extension is inserted inwardly ofthe front end of the body to lie against the iiap 23, while the shorttongues 28-28 respectively engage the outer sides of the iiap extensions22-22 and as they slide downwardly thereagainst they are guided to aposition into pockets 29 formed between the extensions 22 and the outerends of the outer front wall I6. When the cover reaches the limit of itsclosing movement, the ends of the fold 24 enter the notches 29, thuslimiting the closing movement of the cover and providing a support forthe front end of the cover although the tongue 21 terminates short ofthe bottom I2 of the box body II. The extensions 22-22 also act as stopsfor preventing the inward swinging of the front cover iiap 20. Thetongue extension 20 serves to close the open portion of the cut-away ornotched front wall I5.

Heretofore in display boxes of this type, the cover relied upon the sidetop aps I1 and the engagement of the cover flap with the bottom wall ofthe box body for the support of the cover against any'pressure appliedthereto when the cover is in closed position. Such construction isinsucient to withstand the pressures to which boxes are subjected whenstacked for shipment, resulting in the inward crushing of the cover anddisiigurement of the display box as a whole. Whereas in my constructionthe side iiaps I1 act as a seat for supporting the intermediate portionof the cover I8, the interfitting of the notches 29 with the ends of thelow front wall of the box, act to rmly support the cover againstaccidental inward crushing.

In the form of the invention shown in Figures l to 5, the cover I8 whenclosed is free to be swung to open position, but in Figures 6 and 7 Ihave shown a slight modification wherein the cover may be lockedinclosed position. The construction shown in Figures 6 and 7 is the sameas that previously described, with the exception that the tonguesdesignated 28-28 are wider than the tongues 28-28 heretofore describedand are notched inwardly to provide hook portions 30 which may be forcedpast the ends of the fold 24 to engage beneath the fold and becomelocked thereto. To open the cover it is only necessary to flex thetongues 28' outwardly to disengage the hook portions from the ends ofthe fold 24.

In Figures 8 to 10 inclusive I have illustrated a further modified formof my invention wherein the lapping flaps ISLIE, outer front end wallI6, and an inwardly folded flap 23 are held together by a metal stitchor staple 3|. The iiap 23 is similar to the flap 23 heretofore describedbut it terminates short of the bottom wall of the box body for in thisform the stitch 3I is relied upon to hold the front end of the box inassembled position instead of the interlocking of the infolded ap withthe bottom wall. Also, in this form` of the invention the tongues 28 onthe cover flap are dispensed with and the corners 32 between the tongueextension 21 and front cover ap 20 act as the equivalent to the notches29 and engage the ends of the top edge of the low front wall structureof the box body. Whereas the support for the front end of the covershown in this modified form is substantially the same as that in thepreceding forms, this construction is more diiiicult for an operator tohandle when moving the cover I8 to closed position for the guide tongues28 are absent, and which tongues 28 facilitate the guiding of the longertongue 21 inwardly of the low front wall of the box.

In display boxes of the kind herein set forth, it is customary toprovide the cover I8 with a transverse score line 33 whereby the coverwhen open may be folded upon itself and the front cover iiap inserteddown against the inner side of the rear end wall I4 and the folded coverheld by the rear ends of the side flaps I1-I1 whereby the folded coverwill stand upright and display any advertising indicia which may beprinted thereon. I'hus the box IIJ may be opened and placed upon acounter or in a store window to clearly display the contents of the boxand any advertising indicia printed upon the cover. l While I have shownand described several embodiments of my invention, I wish it to beunderstood, that such further modifications as come within the spirit ofthe invention may be resorted to if desired.
